... he swallowed the with the nanoparticles in their decorated with and ideas are molecules that attack other molecules ... to course through your body ... because the core of these particles are magnetic ... you can call them somewhere you can if you look at your wrist right here you'll see that there's a superficial veins ... expecting a magnet there you can track them ... and you can ask them what they saw ... me ask them ... hey wait to see ... did you find counts are good to see something looks like a fragile the pot for a heart attack did you see too much sodium ... with just the ... under contract in the headlights I think that the Global X research labs ... I'm WS J T live conference to strangle the latest project ... The nanoparticles that fits the human body for cancer and other diseases ... could it be just the technology doctors need to diagnose patients earlier here tell us more is Daddy SJ help ... Report or grumblings lamp ... from Acer being here ... the two years or so when you hear about something like this that sounds a little crazy swell of the skillet and a move throughout your body it does this seem like it could be in control to help ... the help doctors diagnose patients going on ... we strongly error of morning in a lot of ways to figure out the genetically in molecular Lee what is going on with their bodies ... in hopes of ... finding some clues ... well ... you ... know that so ... we will do in the future with a rule were likely to get sick or not and then ... maybe what kinds of strategies we can take ... to ward them off ... but there's a whole lot of information we don't know ... about ... those molecules that the ... Mr Condon said Baldwin what will we see ... what will we see ... the wet ... weather Nestle's questions ... and we're not really wants me to know the answers board really know what we need to do ... two ... it to respond to that information ... in a decent challenge is in getting a device like this prove something that you have to smile and kind of move throughout your body are there any new medical costs are concerns that for sure in others Nanotechnology tests already on the market ... they're not doing very well because ... lots of ... that sort of disruptive technology has really done this disruptive workout ... perhaps it will ... but those tests are done on blood tissue or tissue or samples taken from outside the body ... this he's talking about a pill year ... filled with these tiny tiny little ... particles ... of the logo ... who knows exactly where in the body Darden to be able to ... call him or hate them with different structures that will hone in on differed ... from sales ... and I think that kind of idea is established ... but still ... what happens to them in the body however that last home to the clear ... aam ... the FDA for sure is can one know that ... we've had of technology has been on the market for little while ... off camera local camera ... that you know it's can report it until ... you actually can take a look to divest a trend ... it took awhile to get that on the market ... that ... passes for the body of sensitive information but didn't stay in her pool for a lot ... so there's lots of ... you know when you put something about it because they do the FDA wants to make sure ... that safety and the biggest hurdles for that they'll be interesting to see people are excited about this are creeped out by Iran with that thing say much for being here ... the
